Abstract:
Disclosed herein are a method of transmitting a frame for supporting a legacy system, and a method and an apparatus of searching a cell using the same. A frame including a first frequency band for supporting a mobile communication system and a second frequency band for supporting a legacy system and having a total frequency band larger than the second frequency band is generated. Primary broadcasting information related to a frequency bandwidth is transmitted through a broadcasting physical channel of the second frequency band.
Abstract:
A synchronization signal transmitting apparatus generates a plurality of different primary synchronization signals that are transmitted in an ultra frame unit within one super ultra frame and generates one secondary synchronization signal that is transmitted in a frame unit within one super ultra frame.
Abstract:
A cooperation MIMO transmitting or receiving method is disclosed. A master terminal calculates a first signal to interference plus noise ratio (SINR), which is SINR between the mater terminal and a base station or between the master terminal and another cluster, and the master terminal calculates a second SINR, which is SINR between a slave terminal and the master terminal. Here, the master terminal forms a cluster with the slave terminal when the second SINR is higher than the first SINR.
Abstract:
Disclosed herein are a cooperation MIMO transmitting/receiving method and a terminal for supporting the same. A master terminal forms a slave terminal and a cluster performing cooperation communication. The master terminal transmits some data of data to be transmitted to a slave terminal and shares the some data with the slave terminal, and the slave terminal transparently transmits data transmitted from the master terminal to a target node.
Abstract:
Disclosed are a method and a terminal for a distributed access. The terminal maps data channels to be allocated in a plurality of data channels included in a frame and map scheduling priorities. In this case, the terminal determines positions of resources of a first message as a resource request message and a second message as a response message for the first message in the first channel.
Abstract:
Disclosed herein is a method for resource access, including: selecting at least one data sub-frame among a plurality of sub-frames included in a frame; transmitting the data from the data sub-frame; and transmitting a blocking signal from a previous sub-frame of the data sub-frame.
Abstract:
A reception terminal receives information indicating whether a service flow requires in-order delivery and a maximum time during which data not yet received is to wait in a case in which in-order delivery is required, from a transmission terminal, restores service data units (SDUs) from protocol data units (PDUs) received from the transmission terminal with respect to the corresponding service flow, and transmits the restored SDUs to a higher layer according to sequence numbers of the received PDUs in order.
